JSP :: Read Name And Gender From HTML Form And Provide Feedback
May 12, 2014
For a class assignment I have to write a JSP program that will get the name and gender from a simple HTML form and then provide feedback to the user such as "Enter your name" if they leave that field blank. The HTML form has a textField for the name and two radio buttons for male and female, plus a submit button. We covered JSPs only briefly so along with being a Java newbie, JSPs are pretty foreign. I had written the same program as a servlet so I attempted using the similar code for the JSP. I'm using switch to get the gender from the radio buttons but that doesn't seem to work as I keep getting the response "Please select your gender".
My JSP code:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ page import="java.util.ArrayList" language="java"%>
[Code] ....

I have a very simple HTML form with a textField for a name, and add button to add the name to a MySQL database, and a sort button to sort the names in the database and display them. I almost have it working, however when I hit the "sort" button; I get the message that appears after a user clicks the add button along with the sorted list of names. It looks like this:
Please go back and add a name or sort.
Bill Jones
David G
Debbie Downer
Jane Doe
Joe Smith
John Doe
Mike Jones
Paul Smith
Susan Jones
What I have to change on my code to make just the list show up by itself when the user clicks sort?
My servlet code:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.sql.*;

I am having an issue with retrieving "grouped" data from HTML form to servlet. I will describe the scenario below.
In companies, they record the salary of the employees once a month.When they record it, they do not do it by visiting each an every employees personal "profile" (or whatever according to the system). Instead what they do is apply the salaries of all of them in one page.
To do the above thing they prefer excel like tabular sheets. Now, I have a html form, where the form content is a table. One row is dedicated to a one employee.
Below is my form.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
[Code] .....
As you can see, I have wrapped every row with a `<tbody>`. The `value` attribute of the `<tbody>` will contain the employee id. Once the form is submitted, the below servlet will capture it.
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
[Code] .....
What I was trying is get the `value` attribute of `<tbody>` (so I can identify the id of the employee) and get the data inside that `<tbody>`. However this didn't work, because I ended up with `NullpointerException` because it failed to read the `<tbody>` value.
So, how can I pass the data from table to servlet where it can clearly understand that one row is representing data belong to a one employee? If this is not the way to do it, I am also open for other methods.

I just started in java programming and into Arrays multidimensional. I started a simple 2 dimensional array with 5 names with genders. I 'm having issues because it does not want to print out the names with correct genders Male/ Female. The simple program should print out the 5 names with gender type.
example:
Jack - Male
Sally - Female
Dave - Male
Sue - Female
Brian - Male
Here is what I came up with so far:
public class Multiname
{
public static void main(String[] args)
{
//String[][] multiname;
String [][] multiname =
[Code] .....
This is the result:
multiname : Jack
multiname : sally
multiname : Dave
multiname : Brian
multiname : Sue
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
at MultiD.main(MultiD.java:29)

how can I provide a lock to a CSV file while creating the CSV file using java application and how to restrict the user to open CSV file manually instead of opening the file using java application(Swings and Hibernate). That means instead of opening the file manually the user has to use java application to open that CSV file.

I have a file containing a line that starts with professors name followed by the subject name and the semester when it will be taken.I have to Implement Stack to provide input in the file , read the file and then it will ask for a user input of Professor Name and the Semester. The program will determine the subjects taken by the professor and if there is Classes of the same professor in the user provided Semester.
I only know how to read line by line in a text file and not a single string in a file that then will determine the subject taken by that professor and that semester.

I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.

Part of my app is to provide an interface to an operator to manage multiple printers of smart cards.
A JSP page displays all printers and each printer has a print button.
I want the operator to press several buttons and each button pressed starts a thread.
Threads should run in parallel and pressing a button does not cancel the processing of the previous button.

I have a button on UI which adds messages and when the user clicks on it the form gets submitted, meanwhile the user is clicking on refresh(F5) multiple times which is causing the same message to be displayed multiple times. To resolve this , I am converting the form from a synchronous submit to Asychronous but it is still not working. Below is the code:
Code before:
<td><input class="buttonred" type="submit" value="Confirm Add" name="submit_message"></td>
<s:form action="upd-message" method="POST" validate="true" onsubmit="validateMsg();return false;" enctype="multipart/form-data">
function validateMsg() {
var frm = document.forms["upd-message"];
frm.actionType.value=message;

I am creating a search module page. It has many input ext field and a search button.
On my jsp, I have the following:
<label>Reference ID:
<input id="referenceID"
name="referenceID"
type="text"
value="<c:out value="${transaction.refId}" />"/>
</label>
On my servlet, I have the following (code fragment):
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Transaction transaction = new Transaction();
transaction.setRefId(request.getParameter("referenceID")== null || request.getParameter("referenceID")== "" ?null:Long.parseLong(request.getParameter("referenceID")));
request.setAttribute("transaction ", transaction );
}
Is there any alternative on executing request.getParameter on the id's of input text in order to set it on the Transaction bean so that the values will display on the user when the page reloads?

I do not think this is possible, but I'd like to confirm. If I have an HTML page that has an embedded Java applet, and that applet in turn renders an HTML document (within the applet window), is the HTML *within* the applet part of / accessible through the DOM for the parent page?

i have got an array which has come from a text file.
Parts of the array have been placed into a string.
So string one will have about 50 different values which I am able to print into the console using System.out.println("FirstString"); This prints all of the variables from the array so I end up with 50 words.
I am now trying to get this into a HTML document.
I have correctly done this and I get some out put when the webpage opens.
My problem is that I only have 1 work which is displayed.
